Abstract
A liquid crystal display panel includes in the following order: a first substrate including pixel electrodes; a liquid crystal layer; and a second substrate including a counter electrode. The liquid crystal display panel includes pixels each including at least four alignment regions that provide different tilt azimuths to the liquid crystal molecules. The four alignment regions are arranged in a longitudinal direction of the pixels. The pixel electrodes are each provided with linear slits. The slits are formed in a region between one pixel edge of each pixel in the longitudinal direction and a center line of the pixel in the transverse direction in each alignment region. The liquid crystal molecules are aligned in a direction substantially perpendicular to the first substrate and the second substrate and at a tilt in the respective tilt azimuth directions with no voltage applied to the liquid crystal layer. The liquid crystal molecules are at a twist angle of substantially 45° or smaller. Upon application of voltage to the liquid crystal layer, the liquid crystal molecules are to be more tilted in the respective tilt azimuth directions and the tilt azimuth of each liquid crystal mo…
